TECHNICAL FIELD

This application relates to the field of electronic technologies, and specifically, to a graphic display method and apparatus.

BACKGROUND

As portable terminals gradually become popular and more intelligent, portable terminals are no longer used as communications tools only, but instead are used as intelligent terminals that integrate work, life, and entertainment. To satisfy users' requirements, an intelligent terminal may include a main planar display screen and a lateral curved display screen. Terminals may have different morphological features. Different from a conventional planar display screen, a curved display screen has particular curvature. A curved screen may expand a display area of a terminal and at the same time has a more attractive look.

However, it is found in practice that a touch operation cannot be intuitively displayed on a curved screen, and a misoperation rate of the touch operation is relatively high.

DESCRIPTION OF EMBODIMENTS

An embodiment of the present invention provides a graphic display method that may be applied to various terminal devices, for example, terminal devices such as a smartphone, a camera, a media player, and a tablet computer. The terminal device may be an electronic device having a curved screen. The curved screen includes a main planar display screen and a lateral curved display screen. The lateral curved display screen is an edge part of the curved screen, as shown by areas B1 and B2 in FIG. 1 . The main planar display screen is a part other than the lateral curved display screen on the curved screen, as shown by an area A in FIG. 1 . In the graphic display method in this embodiment of the present invention, a touch graphic and an operation indication graphic may be displayed based on a touch operation, to improve operation experience of a user. Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a graphic display method according to an embodiment of the present invention. The graphic display method may include the following steps:

S101: A terminal detects a touch operation on a screen when there is a to-be-processed event.

S102: The terminal obtains touch point coordinates of the touch operation.

S103: The terminal displays, in a position indicated by the touch point coordinates, a touch graphic used to indicate the touch operation.

S104: The terminal displays, on the screen based on the touch point coordinates, an operation indication graphic corresponding to the to-be-processed event.

In this embodiment of the present invention, the to-be-processed event may include an incoming call, unlocking, SMS message editing, alarm clock editing, an operation of other application software, and the like. The touch operation may be an operation of a user's finger, stylus, palm or the like sensed by the terminal by using a touch sensor. Coordinates of a contact point of the finger, the stylus, the palm or the like on a touch display screen are touch point coordinates of the touch operation. The touch graphic is a touch area displayed based on the touch point coordinates of the finger, the stylus, the palm or the like on the touch display screen. The operation indication graphic is an area correspondingly displayed based on the touch graphic and the to-be-processed event. For example, as shown in FIG. 3 , if the to-be-processed event is an incoming call, a terminal detects a touch operation on a screen, obtains touch point coordinates to display a touch graphic, and correspondingly displays an operation indication graphic on the screen. Two operation indication graphics including an answer graphic and a reject graphic are respectively located on two sides of the screen. As shown in FIG. 4 , if the to-be-processed event is SMS message editing, a terminal detects a touch operation such as a swipe operation on a screen, obtains touch point coordinates to display a touch graphic, and correspondingly displays an operation indication graphic on the right side of the screen. The operation indication graphic may be a deletion graphic for deleting an SMS message.

In this embodiment of the present invention, in addition to the touch point coordinates of the touch operation, the terminal may further obtain a pressure value of the touch operation, and adjust sizes of the touch graphic and the operation indication graphic based on the pressure value. Optionally, the size of the touch graphic is positively correlated to the pressure value, and the size of the operation indication graphic is also positively correlated to the pressure value. For example, a usual pressure value of the touch operation is used as a reference pressure value. When the pressure value of the touch operation is greater than the reference pressure value, the sizes of the touch graphic and the operation indication graphic are increased. When the pressure value of the touch operation is less than the reference pressure value, the sizes of the touch graphic and the operation indication graphic are reduced. Optionally, a correspondence between a pressure level and a proportion for enlarging/shrinking the touch graphic and the operation indication graphic may be set in advance, and display proportions of the touch graphic and the operation indication graphic are determined based on a pressure level corresponding to the pressure value of the touch operation.

In this embodiment of the present invention, the terminal may display a touch graphic presentation picture in the position of the touch point coordinates, where the touch graphic presentation picture includes a dynamic picture of the touch graphic increasing in size; and correspondingly display operation indication graphic presentation pictures on two sides of the screen, where each of the operation indication graphic presentation pictures includes a dynamic picture of the operation indication graphic increasing in size. For example, for an electronic device having a curved screen including a main planar display screen and a lateral curved display screen, the terminal may display a touch graphic presentation animation of the touch operation in the position of the touch point coordinates on the main planar display screen, and display an operation indication graphic presentation animation corresponding to the to-be-processed event on the lateral curved display screen. The touch graphic presentation animation may be displaying the touch graphic of the touch operation in an enlargement manner in the position indicated by the touch point coordinates on the main planar display screen within a preset time period, and displaying the operation indication graphic of the to-be-processed event in an enlargement manner on the lateral curved display screen within the same preset time period. To be specific, the touch graphic is fully transparent at first and gradually turns fully opaque within the preset time period (preferably 300 ms), and the proportion gradually increases from 0 to 100%. Similarly, the operation indication graphic is fully transparent at first and gradually turns fully opaque within the same preset time period, and the proportion gradually increases from 0 to 100%.

In this embodiment of the present invention, as shown in FIG. 5 , the touch graphic is formed by combining one main circle C1 and one auxiliary circle C2. A formula for combining the main circle C1 and the auxiliary circle C2 is shown in Formula (1):

$\begin{matrix} {{F_{1}\left( {x,y} \right)} = {\frac{R_{1}^{2}}{\left( {x - x_{1}} \right)^{2} + \left( {y - y_{1}} \right)^{2}} + \frac{R_{2}^{2}}{\left( {x - x_{2}} \right)^{2} + \left( {y - y_{2}} \right)^{2}}}} & (1) \end{matrix}$

-   -   where (x₁, y₁) is coordinates of a center of the main circle,         namely, the touch point coordinates, and R₁ is a radius of the         main circle; (x₂, y₂) is coordinates of a center of the         auxiliary circle, and R₂ is a radius of the auxiliary circle;         and R₁/R₂ is equal to a preset ratio k₁.

The radius R₁ of the main circle C1 is related to the size of the touch graphic. The size of the touch graphic is determined by a size of a user's finger or stylus in contact with a display screen. When a finger is used to perform a touch operation, the touch graphic is usually 9 mm to 12 mm. The auxiliary circle is related to the position and size of a protrusion of the touch graphic. When a preset proportion k1 is preferably 0.5, a combined graphic or combined mixed graphic has a better display effect.

In this embodiment of the present invention, the displayed size of the combined touch graphic may be obtained by using an algorithm for reversely determining a critical value. To be specific, the radius of the main circle in the touch graphic is determined based on an eventually displayed size of the touch graphic, to improve an effect of displaying the touch graphic and reduce impact on display of other content on the screen. Based on a critical value determined by using the algorithm for reversely determining a critical value, a part of F₁(x, y) that is greater than the critical value is displayed as the touch graphic, and a part of F₁(x, y) that is less than or equal to the critical value is not displayed. The eventually displayed size or dimension of the touch graphic may be controlled by using the critical value. In this embodiment of the present invention, the critical value is set to 1 by default. For example, the critical value is 1 in a touch graphic during an incoming phone call and unlocking.

In an initial state, the coordinates of the center of the main circle are the same as the coordinates of the center of the auxiliary circle. When the touch operation swipes, a distance from a horizontal coordinate of a center point of the touch graphic to any edge of the screen is negatively correlated to a distance from a horizontal coordinate of a center point of the operation indication graphic to the any edge. The any edge and the operation indication graphic are located on a same side of the curved screen. A ratio of a displacement of the horizontal coordinate of the center point of the touch graphic to a displacement of the horizontal coordinate of the center point of the operation indication graphic may be a fixed ratio k2. The fixed ratio k2 may be a ratio of a radius of a circle in the operation indication graphic to a half of the main planar display screen.

In this embodiment of the present invention, as shown in FIG. 6 , the operation indication graphic is formed by combining one ellipse B1 and one circle B2. A formula for combining the ellipse B1 and the circle B2 is shown in Formula (2):

$\begin{matrix} {{F_{2}\left( {x,y} \right)} = {\frac{R_{3}^{2}}{\left( {x - x_{3}} \right)^{2} + \left( {y - y_{3}} \right)^{2}} + \frac{c^{2}}{\left( \frac{x - x_{4}}{a} \right)^{2} + \left( \frac{y - y_{4}}{b} \right)^{2}}}} & (2) \end{matrix}$

-   -   where (x₃, y₃) is coordinates of a center of the circle B2 in         the operation indication graphic, and R₃ is a radius of the         circle in the operation indication graphic; (x₄, y₄) is         coordinates of a center of the ellipse B1; and c is a focal         length of the ellipse B1, where C=√{square root over (a²−b²)},         and the center of the circle B2 is the center point of the         operation indication graphic.

In this embodiment of the present invention, if the touch operation is a swipe operation, the touch graphic and the operation indication graphic are moved based on touch point coordinates of the swipe operation. A vertical coordinate of a center point of the touch graphic is the same as a vertical coordinate of a center point of the operation indication graphic. If the to-be-processed event includes an unlock event and the touch operation is a swipe operation, an unlock instruction is generated when the swipe operation swipes to a position of the operation indication graphic. Alternatively, if the to-be-processed event includes an incoming call event, an answer instruction or a reject instruction is generated when the touch point coordinates are in a position of the operation indication graphic.

As shown in FIG. 7 , for example, the terminal has a main planar display screen and a left lateral curved display screen. In an initial state, a center of a circle in an operation indication graphic is a left vertex of a minor axis of an ellipse. When a touch graphic is gradually displayed on the main planar display screen in a form of a touch graphic presentation picture, as shown in FIG. 7 , the center of the circle in the operation indication graphic gradually moves from the left vertex of the minor axis of the ellipse to a center (x₄, y₄) of the ellipse. When the touch graphic gradually approaches the operation indication graphic, as shown in FIG. 7 , in a vertical direction, a center point of the touch graphic moves as touch point coordinates continuously change, and the center of the circle B2 in the operation indication graphic also moves with the center point to a right vertex of the minor axis of the ellipse. The vertical coordinate of the center point of the touch graphic is the same as the vertical coordinate of the center of the circle B2 of the operation indication graphic. In a horizontal direction, a distance from the horizontal coordinate of the center point of the touch graphic to a left edge of the left lateral curved display screen is negatively correlated to a distance from the horizontal coordinate of the center point of the operation indication graphic to the left edge of the left lateral curved display screen.

In this embodiment of the present invention, when a difference between a horizontal coordinate of a center point of the touch graphic and a horizontal coordinate of a center point of the operation indication graphic is a preset value, a graphic obtained by combining the touch graphic and the operation indication graphic is displayed, and an operation instruction corresponding to the operation indication graphic is generated. A formula for combining the touch graphic and the operation indication graphic is: F₃(x,y)=F₁(x,y)+F₂(x,y). To be specific, three circles and one ellipse are combined. If the difference between the horizontal coordinate of the center point of the touch graphic and the horizontal coordinate of the center point of the operation indication graphic is greater than a preset threshold, when no touch point coordinates are detected, a touch graphic disappearance picture is displayed in a position of touch point coordinates detected last time, where the touch graphic disappearance picture includes a dynamic picture of the touch graphic decreasing in size; and an operation instruction corresponding to the operation indication graphic is not generated.

A formula for combining a plurality of circles k and a plurality of ellipses n is as follows:

${F\left( {x,y} \right)} = {{\sum\limits_{k}^{1}\frac{R^{2}}{\left( {x - x_{k}} \right)^{2} + \left( {y - y_{k}} \right)^{2}}} + {\sum\limits_{n}^{k + 1}\frac{c^{2}}{\left( \frac{x - x_{n}}{a} \right)^{2} + \left( \frac{y - y_{n}}{b} \right)^{2}}}}$

-   -   where (x_(k), y_(k)) is a center of a corresponding circle,         (x_(n), y_(n)) is a center of a corresponding ellipse, R is a         radius of each circle, and the radii of the circles may be the         same or may be different; and a and b are values of a major axis         and a minor axis of an ellipse, and c is a focal point of an         ellipse.

It can be learned that, in this embodiment of the present invention, the terminal detects a touch operation on a screen when there is a to-be-processed event; obtains touch point coordinates of the touch operation; displays, in a position indicated by the touch point coordinates, a touch graphic used to indicate the touch operation, and displays, on the screen based on the touch point coordinates, an operation indication graphic corresponding to the to-be-processed event. In this way, the touch graphic and the operation indication graphic are displayed on the screen to enable a user to see a current to-be-processed event in a more intuitive and vivid manner, thereby reducing a misoperation rate of a touch operation and improving operation experience of the user.

Referring to FIG. 8 , FIG. 8 is a schematic flowchart of another graphic display method according to an embodiment of the present invention. In the graphic display method shown in FIG. 8 , for example, a user swipes rightwards to answer a phone call. As shown in FIG. 9 , it is assumed that an initial press made by the user on a display screen is at the center of a main planar display screen. To be specific, a center O1 of a main circle in a touch graphic is the center of the main planar display screen. O4 and O5 are initial positions of centers of circles in operation indication graphics when the user makes no press. In this case, the operation indication graphics are not displayed. O2 and O3 are positions of the centers of the circles in the operation indication graphics when the user makes the initial press on the display screen but has not moved the finger yet. At this time, the operation indication graphics start to be displayed. O6 and O7 are the farthest ends to which the centers of the circles in the operation indication graphics can move when the touch graphic moves with the user's finger to a left lateral curved display screen or a right lateral curved display screen. At this time, a displayed size of the operation indication graphic is largest. The graphic display method may include the following steps.

S201: A terminal detects a touch operation on a screen during an incoming call.

S202: The terminal obtains touch point coordinates of the touch operation.

S203: The terminal displays a touch graphic presentation picture in a position indicated by the touch point coordinates.

S204: The terminal displays, on the screen based on the touch point coordinates, an operation indication graphic presentation animation corresponding to a to-be-processed event.

In this embodiment of the present invention, the terminal generates a touch graphic of the touch operation based on coordinates of O1 (the coordinates of the touch point at this time) and Combination Formula (1) for a touch graphic, and generates an answer graphic and a reject graphic for the incoming call based on coordinates of O1, O3, and O2 and Combination Formula (2) for an operation indication graphic.

S205: When detecting a rightward swipe operation for answering the incoming call, the terminal changes a position of a touch graphic on a main planar display screen and positions of an answer graphic and a reject graphic on two lateral curved display screens based on touch point coordinates of the swipe operation.

S206: If a difference between a horizontal coordinate of a center point of the touch graphic and a horizontal coordinate of a center point of the answer graphic on the right lateral curved display screen is less than or equal to a preset threshold, the terminal displays a graphic obtained by combining the touch graphic and the answer graphic and generates an operation instruction corresponding to the answer graphic.

The preset threshold may be used to determine whether an answer condition is satisfied or may be used to determine whether a combination condition is satisfied. Optionally, a threshold of the answer condition may be the same as or different from a threshold of the combination condition.

S207: When detecting no touch point coordinates, the terminal displays a touch graphic disappearance picture and an operation indication graphic disappearance picture in a position of touch point coordinates detected last time.

The touch graphic disappearance picture includes a dynamic picture of the touch graphic decreasing in size. The operation indication graphic disappearance picture includes a dynamic picture of the operation indication graphic decreasing in size.

When the coordinates of the center point of the touch graphic, namely, the touch point coordinates, move from O1 to O3, the center point of the answer graphic on the right lateral curved display screen moves from O3 to O6. When the touch point coordinates reach the position of O3, the center point of the answer graphic moves to the position of O6, and a protrusion of the answer graphic reaches a largest height. A center point of the reject graphic on the left lateral curved display screen moves from O2 to O5, and the reject graphic gradually changes from an initial protruding state to a non-protruding state. When the touch point coordinates continue to move from O3 to O4, the center point of the answer graphic on the right lateral curved display screen moves from O6 to O4. The protrusion of the answer graphic gradually changes from the largest height to a non-protruding state.

It should be noted that when the answer condition is met and the touch graphic and the answer graphic are not combined, although the touch operation of the user does not leave a screen, the touch graphic and the answer graphic disappear. If a distance from a horizontal coordinate of a position in which the touch operation of the user ends to a right edge of the right lateral curved display screen is greater than a preset threshold (for example, the preset threshold is one fifth of a total width of the main planar display screen), unlocking fails, and both transparency and scaling ratio of the touch graphic change from 1 (100%) to 0. The touch graphic disappears in a current position, and a disappearance time period is equal to a preset presentation time period. Meanwhile, the center point of the answer graphic moves from the current position to O4, the center point of the reject graphic moves from the current position to O5, and the answer graphic and the reject graphic gradually disappear. Meanwhile, transparency of ellipses in the left lateral curved display screen and the right lateral curved display screen changes from 1 to 0. In other words, the ellipses also gradually disappear.

Referring to FIG. 10 , FIG. 10 is a schematic structural diagram of a graphic display apparatus according to an embodiment of the present invention. The graphic display apparatus may be applied to an electronic device having a curved screen. The curved screen includes a main planar display screen and a lateral curved display screen.
